' navonvme' Be it known that I, THOMAS H. KNIGHT, a citizen of the United States, residin at Atlanta, in the county of Fulton and tate of Geor ia, have invented certain new and useful mprovements in Revolving Book and File Cases; and I do declare the follow ing to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which itapper'tains to This-invention relates to improvements in' book and file cases... j

One object of the invention is to provide a book case of this character whereby the books and papers contained therein ma be entirely closed in and protected from ust, dam ness, or other injury in any form and in w ich the book or paper desired may be readily found andremoved."

Another object'is to provide a revolving book case having combined adjustable file and book holding devices adapted to provide book receiving spaces ofgreater or less width.

With these and other objects in view, the

invention consists of certain novel features of construction, combination and arrangement of arts, as will be more fully described and particularly pointed out in the appended claims. I Y

In the accompanying'drawin s: F igure 1 is a side. view of a book and file case constructed in accordance. with the invention. Fig. 2, is a similar view with the outside cover of the case removed. Fig. 3, is a vertical longitudinal section of the case as shown in Fig. 1. Fig. 4, is a horizontalsection taken between two of the shelves and immediately above the book holders thereon.

Fig. 5, is a detail vertical section on the line 5-5' of Fig. 4. Fig. 6, is a detail perspective view of one of the book holdm and fileforming devices. Fig.7, is a detai vertical section on the line 7-'-7 of Fig. 4, showing the 'manner in which the inner ends of the book holders are secured in place; and

' Fig. 8, is a similar view on the line 8-8 of Fig. 4, showing how the outer ends of the ho ders are ad ustably secured in lace.

Referring more. particular to t e drawings, 1, denotes my, improved case, comprising a base 2, whichmay be of any suitable construction and is here'shown in the form of a stand having a circular top 3, and supportingv legs 4, said legs being preferab y 3003 AND rum 04am.

provided with rollers 5, whereby the book case may be readily moved from one lace to another. Revolubly mounted at its liiwer end in the center of the base 2, is an upwardly projecting shaft 6, the u per end of which is revolubly mounted in the top 7, of a cover or casing 8, which isarranged on the base 2, and may be secured thereto in any suitable manner. The casing or cover 8, may be formed of sheet metal,wood, glass, or other suitable material and is provided in one side with a suitable open' 9, to rmit the removal and replacing of t e boo s and papers, said opening being covered by a sultable door 10, which may be slidably t), ormay be hinged as shown in thedraw- IIXO'S.

011 the shaft 6, is arran ed a series of circular shelves 11, each she f being provided on its under side with an annular flange or collar 12, in which is arranged a set screw 13, adapted to be secured in engagement with the shaft 6, whereby the shelves are adjust-ably secured in position thereon. By thus securing the shelves to the shaft they may be ositioned at any desired distance from eac 1 other, thus providing for the accommodation of books of diflerent heights or lengths. On each of the shelves 11, is arranged a centrally disposed circular receptacle in the center of the bottom of which is formed an opening corresponding to the opening in thecenter of the shelves to permit the passage of the shaft 6, therethrough. The rece tacles 14, are provided to form an inner we 1 or stop against which the inner edges of the books engage when in place on the shelves. The receptacles 14, are also adapted to receive papers or other small articles and thus serve a twofold purpose. The receptacles are each provided around its lower edge with a downwardly extending flange 15, which projects a suitable distance below the bottom of the receptacle and said flange is provided with a series of closely arran ed a ertures 16, the urpose of which wil hereinafter appear. he receptacles 14, are preferably secured to the shelves by screws or other suitable .fastening devices which are passed through the bottoms of the receptacles and screwed into engagement with the shelves as shown.

On the outer edges of the shelves are secured metal strips 17, the lower edges of Specification o! Lotte" Patent. Patentd'sept, 13,- 191Q,

mounted to cover and uncover theopening engage the lower sides of the shelves ad Ijacent to their outer edges as shown. he 11 per edges of the stris 17, are extended a ove the to s of the s elves and are bent inwardly an downwardly into engagement with the upper sides of the she ves, sa1d bent edges thus each forming a hollow bead, which projects a suitable distance above the top of the shelf and extends entirely around the same and serves as a stop to preventbooks or other objects from sliding off from the shelves when they are revolved, and also serves another purpose hereinafter described. I

The combined book holders and paper files preferably-consist of strips of metalof suitable width bent upon themselves mldway between their ends to form V-shaped partitions 19, which, if desired, may be covered with any suitable fabric. The outer ends of the V-shaped partitions are preferably bentinwardly at right angles while the lower edges of the strips are bent inwardly at right angles and form flanges which engage the tops of the shelves as shown.

Secured to the inner folded end of each partition 19, at the lower corner thereof is a longitudinally projecting pin 20, which is adapted to be engaged with one of the apertures 16, formed in the flanges 15, on the bottom of the center receptacles 14, thereby holding the inner ends ofthe partitions in place. On the outer ends of the V-shaped partitions are arranged longitudinally projecting pins 21, which are adapted to be engaged with notches 18, formed in the beads on the upper edges of the strips 17, thereby holding the outer ends of the -shaped partitions in place. The pins 20 and 21 maybe engaged with any of theapertures 16, and notches 18, thus permitting the partitions or book holders to be shifted or moved to any ers.

desired position on the shelves to increase or diminish the space between the holders thus providing for the accommodationsof books of different thickness, which, when placed on the shelves will be held in position by the adjacent portions of the partltions or hold- The spaces between the side members of the holders or partitions are employed as file holders in which letters or other pa ers may be conveniently filed away an to which access may be rea'dilyhad. The file space between the side members of the partitions o'r holders may be increased or diminished at will by spreading the ends of the members apart or springing the same together. The material from which the holders are formed is suificiently resilient and the pins 20 and 21 are sufiiciently flexible to permit the same to be readily disengaged from the aperture 16 and the notches 18 to' permit the-holders to be moved or adjusted to the desired position on the shelves.

By means of a book case, constructed as justed position.

herein shown and described, the books and spare kept therein are securely protected rom injury and by revolving the shelves, any boo or paper desired may be readily found and removed through the door opening 9, in the side of the case orcovering 2, and if desired, the various spaces between the partitions or holders and between the side members thereof may be numbered and a catalogue or list of the same prepared and hung on the outside of the case or at some convenient point so that the position in the case of the book or paper desired may be readily ascertained and the shelves turned to bring said space opposite the door in the case through which the book or paper may be readily removed.

From the foregoing description taken in connection with the accompan ing drawings,

the ronstruction and operatlon of the invention will'be readily understood without requiring a more extended explanation.

Various changes in the form, proportion and the minor details of construction may be resortedto without departing from the principle or sacrificing any of the advantages of the invention, as defined in the appended claims.

Having thus described my invention, what I claim is: j

1. In a book case of the character described, a base,' a casing arranged on said base and having an opening in one side, a closure for said opening, a supporting shaft revolubly mounted vertically in said casing, a series of shelves adjustably secured on said shaft, a receptacle arranged on each of said shelves around said shaft and adapted to limit the inward movement of the books, a series of laterally yieldable partitions arranged on the shelves to provide spaces to receive the books, and means to ad ustably secure'said partitions in lace.

2. Inv a book case, a ass, a. casing arranged on said base, a supporting shaft revolubly mounted in said base and easing, .a series of circular shelves adjustable vertically on said shaft, annular concentrically arranged receptacles secured to the center of the shelves around said shaft, an apertured flange formed on the lower side of each receptacle, binding stri s arranged around the outer edges of said shelves, said strips having right angularlybent lower ends adapted to engage the lower sides of the shelves and upwardly extending flanges bent inwardly and downwardly to form beads around the edges of the upper sides of the shelves, said beads having a series of notches formed on their inner sides, and a series of partitions arranged on said shelves and having means for engaging the apertures in the flanges of said annular receptacles and the notches in said beads to secure said partitions in ad- 3. In a book case of the character de scribed, a base, a casing arranged on said base, a supporting shaft revolubly mounted in said casing and base, a series of shelves adjustably secured to said shaft, an annular concentrically disposed receptacle arranged in. the center of each of said shelves and around said shaft, said receptacle having a downwardly projecting annular flange provided with a series of closely spaced apertures, an annular bead arranged around the outer edge of each shelf, each bead having formed therein a series of notches, a series of combined book and file holders arranged on said shelves, said holders each corn rising a V-shaped partition formed. of yiel able material, and longitudinally projecting pins arranged at the inner and outer ends of the partition, said pins being adapted to be engaged with the apertures in said central receptacle and with the notches in the bead around the edge of the shelf, whereby the holders are held in their adjusted positions on the shelf, and the sides of the partitions held at the desired distance apart to form file holders of greater or less width.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.
